Abstract
A chair having a base adapted for support on a floor, a seat-back arrangement for accommodating an occupant, and an upright telescopic height adjustable pedestal assembly connected vertically between the base and the seat-back arrangement for supporting the latter and permitting the height thereof to be vertically adjusted. The height adjustable pedestal assembly include a first height adjusting mechanism having a predetermined vertical stroke defined between upper and lower stroke limiting positions for permitting the height of the seat-back arrangement to be adjusted to any position along said stroke; and a second height adjusting mechanism defining at least upper and lower vertically-spaced range positions for permitting the vertical length of the pedestal assembly to be respectively increased and decreased, whereby the seat-back arrangement can be subjected to the predetermined vertical stroke of the first height adjustment mechanism when in either of the upper and lower range positions. The first and second height adjusting mechanisms are connected vertically in series, and each is independently operable.
